If you use macOS Catalina or later (10.15.5 +):

You will need a USB drive the first time you connect your vehicle to W-Fi. After you

connect and your vehicle's software updates, you can set up connections to new Wi-Fi

networks using the USB cable in the box.

How to use a USB Flash Drive to Connect your AWS DeepRacer

Use a Firefox browser to connect to deepracer.aws or the device’s wireless IP

(Chrome is not supported).

Get rolling in approximately 15-20 minutes

Next: Test drive

Check for visual cues that your sensors are ready: Is your LiDAR spinning? Is its LED lit?

Test Drive

1. Enter vehicle IP address to access your vehicle on an internet browser

2. Enter password

Note: This is an example, not your vehicle IP address. If you do NOT have an IP address go to the AWS DeepRacer Getting Started Guide

Note: Found printed on the bottom of your vehicle

https://192.12.68.04

Use any device with a browser to drive your AWS DeepRacer. Connect your device to the same Wi-Fi network as your AWS DeepRacer.

Next: Test drive continued

If you use macOS Catalina or later (10.15.5 +):

You will need a USB drive the first time you connect your vehicle to W-Fi. After you connect

and your vehicle's software updates, you can set up connections to new Wi-Fi networks

using the USB cable in the box.

How to use a USB Flash Drive to Connect your AWS DeepRacer

Use a Firefox browser to connect to deepracer.aws or the device’s wireless IP

(Chrome is not supported).

Test driveNote: Ensure that the vehicle is switched on.

Look beneath the camera viewfinder to find your sensor connection status. The connection is successful if you see green check marks. The LiDAR view finder is switched off by default. Switch it on to verify that it's connected.

Next: Test drive continued

Move the joystick in the forward direction and watch how the vehicle responds. Does the vehicle move in the forward direction?

3. Try autonomous mode

1. Choose the Autonomous driving mode. Load a sample model using the drop down or load your own trained model.

2. Press Start vehicle button

3. Gradually increase the Maximum speed % until model begins to move

Optimizing a trained model for transfer to a physical AWS DeepRacer vehicle can be a challenging learning process. It requires iterations through trial and error. For more tips, see Optimize Training AWS DeepRacer Models for Real Environments

Train reinforcement learning (RL) models

Train your own RL models and watch training in simulation. Evaluate models and download models to your AWS DeepRacer to test on tracks.

When loading models on your vehicle make sure the sensor configurations match. Models trained with LiDAR and stereo camera need to run on vehicles with LiDAR and stereo camera.
